The present invention not only can low-cost processes aged refuse in MSW landfill percolate waste water, garbage compression station extruding waste water, NF/RO membrane concentration liquid height salt high-COD waste water, and makeup waste water can be processed, five metals Cutting Liquid Wastewater, cleaning emulsifiable oil waste water, electro dipping waste water, fruit jelly pickles height salt food wastewater, agricultural chemicals waste water, brewage leavened food waste water, five metals pickling waste water, pharmacy waste water, oil-field well-drilling waste water, black liquid and coking chemical waste water, and be more suitable for processing difficult volatilization, difficult degradation humic acid, Mierocrystalline cellulose, heterocyclic hydrocarbon, aliphatic hydrocarbon, aromatic hydrocarbon, many phenol, the organic pollutant wastewaters such as halohydrocarbon are to Treated sewage reusing, and reclaim soda acid thing, energy-saving and emission-reduction, cleaner production, recycling economy.
The present invention not only the residence time short, eliminate ammonia foul smell and can process containing high concentration organic contaminant waste water, heavy metal containing sewage, and carry out can also desalting treatment to containing sewage with high salinity (process more than saliferous 500PPM-300000PPM); This technology can not only be continuous, stable operation, also have running cost low, floor space is little, and power consumption is low waits the advantage of energy-conserving and environment-protective.
Below the present invention is described in detail, but obviously, those skilled in the art can carry out various changes and improvements, and not deviate from the scope of the present invention that appended claims limits.
